George, castellanus is a species within four genera. Contrails, while recognised, are not to my knowledge a formal cloud type. Hence when discussing (young) contrails I feel one should not use formal terminology; if the contrail matures it can transmogrify (you might find a better word) into a formal cloud type with appropriate terminology.
But it’s not for me to say what you can or can not have. Glad you seem to have an enquiring mind and enjoying it.
Rather cute, George. I am not sure about ‘castellanus’, but they certainly have a crenellated or turreted look. The old ICA talks of ‘pendant swellings like inverted mushrooms’. But yours are not inverted.
Your next challenge, should you choose to accept, might be the eddies from propeller- and wing-tips.
We live and learn, George – the new ICA has a neat feature; when I followed your link and clicked on spissatus the ICA highlighted the spissatus within a red rectangle.
But cirrus spissatus just means optically thick cirrus and I don’t think Roger’s cloud is that high. I will stick with the simple virga.

Different guy – Emily Endean – had Stourhead pic in The Times, UK, 1NOV2017, but I loved this Brighton pic

Well, I searched ‘blueberry’ after his famous ‘Blueberry Hill’. It gave me J Claveau in Art, I know not why; being in Art I noticed this latest one which happened to be within my stamping ground, so… At least it’s fairly blue, though not hilly.

Hugh Montgomery, co-author, discussed this 2017 report on climate change on BBC Radio 4, Inside Science today. He said a big insight for him was that improving things for people was equally good for climate – hence the concentration on data relating to where people lived instead of the major part of the globe where there are no people, just water perhaps.
The Angelus

This talk is by my favourite lecturer, Neil MacGregor. He focuses on prayer, reflecting on how this most highly individualized of activities is also a profoundly communal act.
Likewise, cloudspotting, methinks. MacGregor talks of the angelus bell being rung to remind people to stop what they are doing and pray – a moment of silence in prayer perhaps. What might be the cloudspotting equivalence? What might remind us to stop and look up?
I can only think of setting an alarm on your smartphone.
Well, I was half joking, George. The quote below came from a quick search which showed Saharan dust over Florida in 2012.
‘Beautiful sunsets are observed since the Saharan dust clouds resides so high in the atmosphere. The dust particles act to scatter certain wavelengths of light, allowing red hues to be illuminated.’

I would not disagree, George. The new ICA does not recognise mackerel. Undulatus.

Yes, certainly is, Paul. Thanks. But isn’t there a typo – should be eastward?
‘Pushed by jet stream winds, the line of clouds began to extend westward from Asia on October 12’
The virga falling out of cavum seems to be white (supercooled perhaps and hence medium or above in height); Roger’s seems fairly low and there is no distinct hole..
Hey, hey, Roger, a great capture – I wish I could put a name to it. Any suggestions, anyone? My first thought was Prince of Wales’ Feathers. Then I thought it would make a nice mono for the Black and White thread. Then I thought it ought to be what is now called cavum (another new ICA name)

Or is it just simple virga?Well spotted, George. Just to get thinking about the strange new names in the ICA your K-H has now become fluctus

Don’t forget the first sticky note in the forum index takes you to the new ICA.
